Description

Technical Field

[0001] The utility model relates to the field of electroplating sludge recovery equipment, in particular to an electroplating sludge recovery device. Background Art

[0002] The sources of electroplating wastewater are generally plated cleaning water, waste plating liquid and other wastewater, including flushing workshop floors, plate washing water, ventilation equipment condensation water, and various tank liquids and drainage caused by "running, bubbling, dripping and leaking" due to leakage of plating tanks or improper operation and management. A large amount of electroplating sludge will be generated in the process of electroplating wastewater treatment. If it is discharged arbitrarily without treatment, it will cause serious environmental pollution. In addition, electroplating sludge contains many valuable components, and arbitrary discharge will cause waste. Therefore, it is necessary to use electroplating sludge recovery equipment to recycle the sludge to facilitate the subsequent recovery of valuable components from the electroplating sludge.

[0003] At present, a Chinese utility model with announcement number CN215799117U discloses a device for recovering non-ferrous metals and alloys from electroplating sludge, including a drying box and a box door axially connected to one side of the front of the drying box, a tray rack is provided in the inner cavity of the drying box, a tray is provided on the upper end of the tray rack, a first placement groove is opened on the upper end of the tray rack, a rotating disk is axially connected to the four corners of the upper end of the first placement groove, a plug-in hole is opened on one side of the upper end of the rotating disk, a first chain disk is arranged at the lower end of the rotating disk, a second placement groove is opened on the upper end of the tray, and plug-in columns are arranged at the four corners of the lower end of the tray, so that the rotating disk can rotate. After the rotating disk rotates, the tray can start to rotate, so that the sludge placed in the inner cavity of the tray can be better turned over, thereby accelerating the drying rate.

[0004] To sum up, although the recovery device can achieve the purpose of recycling electroplating sludge, there are still certain problems in its use. For example, the recovery device cannot continuously dry the electroplating sludge. When the electroplating sludge is placed on a tray for drying, it is necessary to wait for the drying time, and then re-load and unload after drying. The drying efficiency is low, and the recovery efficiency is low. At the same time, the recovery device cannot crush the electroplating sludge into small particles. When the electroplating sludge is dried, the whole is in block shape, which causes the block sludge to take up more space during subsequent storage, which is inconvenient for subsequent storage.
